PD1 Question 34

Hello All 
Can you tell me How Can I simulate and test this Question In Developer Org?
 
Question 34 ( Topic 1 )       
A developer needs to join data received from an integration with an external system with  
parent records in Salesforce. The data set does not contain the    
Salesforce IDs of the parent records, but it does have a foreign key attribute that can be used  
to identify the parent.       
Which action will allow the developer to relate records in the data model without knowing  
the Salesforce ID?        
          
          
• A. Create and populate a custom field on the parent object marked as Unique.  
• B. Create a custom field on the child object of type External Relationship.   
• C. Create and populate a custom field on the parent object marked as an External ID.  
• D. Create a custom field on the child object of type Foreign Key.   
          
Answer : D
